British Dictionary definitions for differentiation

differentiation

/ˌdɪfəˌrɛnʃɪˈeɪʃən/

noun

1.

the act, process, or result of differentiating

2.

(maths) an operation used in calculus in which the derivative of a function or variable is determined; the inverse of integration See integration (sense 6)

3.

any process in which a mixture of materials separates out partially or completely into its constituent parts, as in the cooling and solidification of a magma into two or more different rock types or in the gradual separation of an originally homogeneous earth into crust, mantle, and core

In calculus, the process of computing the derivative of a function. Compare integration.

The process by which cells or parts of an organism change during development to serve a specific function. The cells of an animal in its early embryonic phase, for example, are identical at first but develop by differentiation into specific tissues, such as bone, heart muscle, and skin. The factors determining the differentiation of any particular cell are not well understood, but in deuterostomes (vertebrates and other complex animals) they include the location of the cell relative to other cells.
